From: Junio C Hamano Date: Thu, 27 Apr 2006 23:21:54 +0000 (-0700) Subject: cache_tree_update: give an option to update cache-tree only. X-Git-Tag: v1.4.0-rc1~45^2~11 X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=2956dd3bd7bd512aa8fce7e55d5eec1e56df99ab;p=git.git cache_tree_update: give an option to update cache-tree only. When the extra "dryrun" parameter is true, cache_tree_update() recomputes the invalid entry but does not actually creates new tree object.
